Gadodiamide (Intravenous route)

Pronunciation:

gad-oh-DYE-a-mide

Brand Names:

Omniscan

Dosage Forms:

Solution

Warnings:

Intravenous route(Solution)

Gadodiamide is not for intrathecal use. Inadvertent intrathecal use has caused convulsions, coma, and sensory and motor neurologic deficits. Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs Avoid use of GBCAs unless the diagnostic information is essential and not available with non-contrast enhanced MRI. NSF may result in fatal or debilitating systemic fibrosis affecting the skin, muscle, and internal organs. Do not administer to patients with chronic, severe kidney disease (GFR less than 30 mL/min/1.73 m(2)) or acute kidney injury. Screen all patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (eg, age greater than 60 years, hypertension, or diabetes), perform lab testing to estimate the GFR. For patients with the highest NSF risk, do not exceed recommended dose and allow a sufficient time period for elimination prior to readministration .

Radiological Non-Ionic Contrast Media

Uses of This Medicine:

Gadodiamide is a magnetic resonance imaging (MRI) contrast agent. Contrast agents are used to help create a clear picture of the body during MRI scans. MRI scans are a special kind of diagnostic procedure. They use magnets and computers to create images or “pictures” of certain areas inside the body. Unlike x-rays, they do not involve ionizing radiation. Gadodiamide is a gadolinium-based contrast agent (GBCA).

Gadodiamide is given by injection before MRI to help diagnose problems in the brain, spine, chest, stomach, hip area, and other parts of your body.

This medicine is to be used only by or under the direct supervision of a doctor.

Before Using This Medicine:

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies—

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children—

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of gadodiamide in children 2 years of age and older. However, safety and efficacy have not been established in children younger than 2 years of age.

Older adults—

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gadodiamide in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving gadodiamide.

Pregnancy—
